Amazing

Can't get this anywhere else let alone for the price. Great quality, use it on my lever arms to simulate a assisted lifted off without a partner in benching. Only suggestion is to add uhmw plastic. Great company to buy from

Really nice for bench

I think it's unreal that these come standard with the light commercial rack. They're so useful for adjusting the bar position before a big bench. My only complaint is that I don't understand why they don't have UHMW coating like the regular J-cups. It's an easy DIY fix though, so they're still well worth picking up if you don't have any. I bought a cheap sheet of 1/8" UHMW off amazon, cut a few strips and used 2 sided gorilla tape to cover all the metal spots and protect the knurling on my beautiful Bells of Steel cerakote power bar 🙂

Makes bench setup easy

Love using these for bench. I never quite get my bench centered perfect under the rack. and this lets me adjust with ease when fully loaded.

Let the Good Times Roll!

These roller J-cups make so much sense. Bench press, incline press, squats all require a centered bar. It's so easy with these j-cups that I believe they should be standard equipment. I LOVE them!

Roller J Cups

Great, they allow me to position the bar exactly where it should go, even with lots of weight on the bar.
